This study aims to analyse resilience and relational dynamics (competitive, cooperative and co-opetitive) within a triadic buyer-supplier-supplier context. Our central goal is to show how a buyer's supplier-supplier relational behaviour leads to and shapes resilience of this triad. We utilised a multiple-design case approach and selected eight buyers and their suppliers from the textile industry in Turkey. By analysing a triadic context from another industry, we conducted validation analyses. Our findings showed a pattern of relationship between the resilience and the relational dynamics of a triad. Built on theory and insights from the cases, we proposed three propositions. We argued that when co-opetition prevails in a triadic context of relations, the triad resilience level is highest. In competitive relational settings the triad resilience level is lowest, and when the relational dynamics are cooperative, the triad resilience level is moderate. This study is the first to introduce and discuss organisational resilience at triadic level. Furthermore, to our knowledge, our insights from cases are among the first attempts to link three types of supplier-supplier relational dynamics to triad resilience via the use of a multiple-design case approach. Therefore, our contributions are likely to extend the organisational resilience and buyer-supplier-supplier relations research. © 2014 © 2014 Taylor & Francis.

An in-depth case of an e-Recruiting system implementation is used while focusing on the level of Human Resource (HR) employees to research unintended consequences during the implementation of Human Resources Information Systems (HRISs). We develop a model that integrates the belief and attitude component of the technology acceptance literature with work-related consequences. We provide evidence for an indirect effect of attitudes toward the HRIS on turnover intention that is fully mediated by job satisfaction. Our results contribute to the literature on systems implementations and technology adoption by suggesting work-related outcomes as important additional success variables. © 2013 Elsevier B.V.

Forest fires are known to severely pertubate the nutrient budgets of forested ecosystems by altering the distribution, element species composition and availability of organic matter and associated nutrients. Although several studies have reported on the biogeochemical effects of fires on soil properties and element pools, relatively few have measured the water-flux driven release of nutrients from the forest floor into the mineral soil by lysimeters following low-intensity duff fires. This study was designed to test the effect of a low-intensity fire on the short-term release of nutrients from two different forest floor types developed under a mixed spruce/pine and a beech forest representing the most prevalent forest types in Germany. We found that even low-intensity fires remarkably promoted the amount of leachable nutrients under beech. Compared to the control, the fire treatment at the beech site significantly enhanced the fluxes of DOC by 75%, of DN, NO3-N, NH4-N and DON by, 233, 123, 380 and 158%, respectively, and by 158% for PO4-P. However, at the coniferous site, flux increases were less pronounced exhibiting enhancement rates for DOC of 38%, for DN, NO3-N, NH4-N and DON of 56, 41, 64 and 57%, respectively, and of 19% for PO4-P. Reasons for the different fire effects on the amount and composition of released elements at the beech and conifer site, might be due to the thicker Oa-layer of the coniferous site likely buffering the element pulses into the mineral soil more efficiently, or to the nutrient up-take by the re-establishing ground vegetation. In essence, the study clearly demonstrated that information on the potential range of short-term variability of matter fluxes induced by ecosystem disturbances is necessary, to understand differing filter and trigger mechanisms caused by varying environmental conditions within and between ecosystems. © 2013 Elsevier B.V.

The aim of this study was to identify the hepatoprotective effects of reynosin, sesquiterpenes from the leaves of Laurus nobilis, against thioacetamide (TAA)-induced apoptosis in primary hepatocyte cultures and an in vivo mouse model. Rat hepatocytes were isolated and pretreated with 0.13, 0.64, or 3.22 μM reynosin and then exposed to 100 mM TAA. Reynosin treatment significantly inhibited TAA-induced apoptosis and hepatocellular DNA damage in primary rat hepatocytes. We observed an increase in levels of antiapoptotic Bcl-2, Bcl-XL mRNA and a decrease in levels of proapoptotic Bax mRNA following reynosin treatment of hepatocytes. Apoptosis in BALB/c mice was induced with intra-peritoneal injection of 200 mg/kg TAA for 2 weeks every other day. Then reynosin (5 mg/kg) and TAA were intragastrically given for 3 weeks every other day. Aspartate aminotransferase and alanine aminotransferase levels in the blood of mice were decreased in the reynosin administration group. Bcl-2 and Bcl-XL mRNA levels were increased, and the Bax mRNA level was decreased in reynosin-treated mice. Thus, reynosin inhibited TAA-induced apoptosis in primary hepatocytes and an in vivo mouse model. © 2013 The Pharmaceutical Society of Korea.

Background The growing global childhood obesity pandemic has not spared lowincome countries like Malawi, where 8% of children below the age of five years are overweight. Globally, regular consumption of sweetened beverages is implicated among the factors that fuel childhood obesity. Despite the growing problem, there are no local studies on any aspect of sweetened beverage consumption among children in Malawi that could help in guiding interventions and public health nutrition policies. Aim We aimed to assess sweetened beverage consumption among school-going children in Chilinde, a densely populated township in Lilongwe, the capital city of Malawi. Methods A total of 60 school-going children whose caregivers gave verbal consent were included, and a structured questionnaire was administered to the caregiver (or other knowledgeable and responsible member of the household) of each eligible child. Results Our results showed that 50 of the 60 children sampled were consuming a wide-range of sweetened beverages on a regular basis on any day of the week, mostly during meal times (n = 23), before going to school (n = 22), and after school (n = 19). One-third of the children were reportedly consuming up to 300 mL of several sweetened beverages per day. Conclusion Like in many countries around the world, consumption of sweetened beverages appears to be common among young school-going children in this urban setting in Malawi. As the country builds public health responses to the growing problem of non-communicable diseases, early preventive interventions among children should be given priority. © 2015, Malawi Medical Journal.

The influence of tuning the laser pulse energy during the analyses on the resulting microstructure in a specimen utilizing an ultra-fast laser assisted atom probe was demonstrated by a case study of a binary Al-Li alloy. The decomposition parameters, such as the size, number density, volume fraction, and composition of δ' precipitates, were carefully monitored after each analysis. A simple model was employed to estimate the corresponding specimen temperature for each value of the laser energy. The results indicated that the corresponding temperatures for the laser pulse energy in the range of 10 to 80 pJ are located inside the miscibility gap of the binary Al-Li phase diagram and fall into the metastable equilibrium field. In addition, the corresponding temperature for a laser pulse energy of 100 pJ was in fairly good agreement with reported range of δ' solvus temperature, suggesting a result of reversion upon heating due to laser pulsing. © 2016 Wiley Periodicals, Inc.

Purpose The effect of the combination therapy of curcumin and the herpes simplex virus thymidine kinase (HSVtk) gene using R7L10 as a carrier was evaluated in a glioblastoma animal model. Methods Curcumin was loaded into the cores of R7L10 peptide micelles using an oil-in-water emulsion/solvent evaporation method to generate curcumin loaded R7L10 micelles (R7L10-Cur), which were used as a carrier to deliver the HSVtk gene. The plasmid DNA (pDNA)/R7L10-Cur complex was confirmed by gel retardation, heparin competition, and dynamic light scattering analyses. Transfection efficiency and cytotoxicity were measured using luciferase, MTT, and TUNEL assays. Intracellular delivery of curcumin was determined by fluorescence and absorbance. In the glioblastoma animal model, the effects of the intratumoral delivery of curcumin and the HSVtk gene were evaluated according to tumor size, immunohistochemistry, and TUNEL assays. Results R7L10-Cur delivered pDNA into the cells more efficiently than PLL and R7L10. In addition, R7L10-Cur delivered curcumin into the cells more efficiently than curcumin alone. The pHSVtk/R7L10-Cur complex induced cell death efficiently both in vitro and in vivo. Likewise, the combination of curcumin and the HSVtk gene using the pHSVtk/R7L10-Cur complex reduced tumor size more efficiently than the pHSVtk/PEI and pHSVtk/R7L10 complexes in a glioblastoma animal model. Conclusion R7L10 is an efficient carrier for delivery of curcumin and the HSVtk gene, which may be a useful combination therapy for glioblastoma. © 2014 Springer Science+Business Media New York.

The purpose of this study was to examine the predictive power of each facet of governance mechanisms on regulation in a Taiwan sample. The sample consisted of 2518 employees from seven utilities sectors. The research found that for all utilities sectors clarity of role was significantly negatively correlated with regulation, while accountability and participation were significantly positively correlated with regulation. Moreover, participation was the only governance mechanism that consistently predicted regulation across utilities sectors. © 2013 Elsevier Ltd.

Inter-professional (IP) education and clinical placements have been identified as educational recruitment strategies to address the health workforce shortage. The research question in this secondary analysis study was, "What are students' attitudes toward working in geriatric environments and as part of inter-professional collaborative teams?" A five-item survey was administered to 47 pre-licensure learners from five different health professional programs (medicine, nursing, pharmacy, occupational therapy and physical therapy). Findings suggest that students want to practise on IP teams, which may influence their graduate first choice of employment. Although stronger evidence is required, offering IP clinical placements may be an important recruitment strategy, especially for those sites traditionally deemed less desirable.

Lightweight spatially aware displays (Tangible Magic Lenses) are an effective approach for exploring complex information spaces within a tabletop environment. One way of using the 3D space above a horizontal surface is to di-vide it into discrete parallel layers stacked upon each other. Horizontal and vertical lens movements are essential tasks for the style of multi-layer interaction associated with it. We conducted a comprehensive user study with 18 partici-pants investigating fundamental issues such as optimal number of layers and their thickness, movement and hold-ing accuracies, and physical boundaries of the interaction volume. Findings include a rather limited overall interaction height (44 cm), a different minimal layer thickness for ver-tical and horizontal search tasks (1 cm/4 cm), a reasonable maximum number of layers depending on the primary task, and a convenience zone in the middle for horizontal search. Derived from that, design guidelines are also presented. Copyright 2012 ACM.
